I’ve been viewing the old TV series 12 O’ clock High (1964-67), and being from those non-PC days, characters do smoke in the series.
In some episodes, the control wheels of the studio B-17 (said to be a real fuselage section) have ashtrays clipped onto the back of the control wheel.
They certainly look like aircraft-grade items, anyone know if the Fortress did indeed have such items?
